Solution :
Given:
The total cost of constructing a house was Rs. 3,60,000 in 1991 and Rs. 8,64,000 in 2001.
Steel = 60°
The total value of the pie chart = 360°
The amount spent on steel in 1991
$=\frac{60}{360}×300000=50000$
The amount spent on steel in 2001
$=\frac{60}{360}×864000=144000$
Hence, the correct answer is Rs. 50,000 and Rs. 1,44,000.
